JESSE G. VINCENT, OF DETROIT, MICHIGAN, ASSIGE'OR T PACKARD MOTOR CARCOMPANY, OF DETROIT, MICHIGAN, A CORPOBATIOIN OF MICHIGAN.

, To all whom it may concern:

Be it known that'I, Jnssn G. VINCENT,

a citizen of the United States, and resident of Detroit, Wayne county,State of Michigan, have invented certain new and useful Improvements inHydrocarbon-Motors, of

which the followingis a specification.

This invention ,relates I to multi-cylinder Qhydrocarbon motors, andparticularly to the construction and arrangement of cylinder blocks,valve mechanism, carbureters, intake and exhaust passages, etc.

One of the objects of the invention is the construction of a'multi-cylinder V motor so that the valves are accessible for adjust-.

I ment and for grinding, 'so that the intake and exhaust passages areconveniently and advantageously arranged relative to the valves and toeach other, and so that a single passages of themotor with as littleexposed carbureter may be connected to the intake p ping as possible.

' Other objects of the invention will appear "from the followingdescription taken in connection with the drawings which form a part ofthis specification and in which Figure 1 is a plan view of a hydrocarbonlnotor made in accordance with this inven-' tion; Fig. 2 is a verticalsection approximately on the line 22 of Fig. 1; and

Fig. 3 is' a side elevation of themotor shown in the other figures.

The invention is illustrated herein in connection with a twelve cylindermotor in which the cylinders are arranged in two blocks of six cylinderseach and positioned on the crank case in V relation. Some of thefeatures of the invention are applicable to otors having a lesser numberof cylinders or to other arrangements thereof.

Referrin' to the drawing, 10 represents generally t e motor base orcrank case comprising principally an upper half 11 and a lower half oroil well 12. Upon the crank blocks or castings are suitably water jack-Specifleition of Letters Patent.

eted as at 1 1, and are provided with water inlet pipes 15 and outletpipes 16.

Each of the cylinders is provided with the usual piston 17 and aconnecting rod 18 connects the piston in driving relation with PatentedDec. 25, 1917.,

the crank shaft 19 mounted in suitable bearings 20 in the crank case 10.

.Inlet and exhaust ports 21 and 22 respectively, are formed in thecylinder blocks in series along the outer sides of the blocks. One ofthe intake ports 21 is shown in Fig. 2 at the left side of the drawing,and one of the exhaust ports 22 is shown at the right hand side thereof.These ports of course communicate with the combustion space 23 of thecylinders and they are arranged substantially horizontally with a cap 24screwed into the cylinder casting immediately above-each of the ports,to thus make the ports accessible for grinding and inserting the valveshereinafter described. Spark plugs 24 may be arranged in these caps 24over the intake valves or otherwise as de sired.

Referring particularly to Fi 2 it will be observed that the intake vaves 25 and.

exhaust valves 26 are herein shown as of the poppet variety and arearranged substantially vertically and in series along the outer edges ofthe cylinder blockswhere they and their connections arenlost accessible:These valves of course control the intake and exhaust ports 21 and 22and are provide'd with suitable springs 27 and push rods 28 beneaththeir stems. The push rods 28 are mounted in sleeves 29in extensionsgears 34. These gears are shown diagrammatically in Fig. 2.

A particularly advantageous arrangement of intake and exhaust conduitsor passages is shown in the-form of the invention herein illustrated.The intake ports 21, of

which there are of course six for each cylinder block, are fed by aconduit or passage 35 which extends longitudinally of each of thecylinder blocks adjacent their outer edges, or as shown particularlyin,Fig. 2 these conduits 35 are arranged between the cylinders properand the valves. In the drawings these conduits 35 are shbwn formed as anintegral part of the cylinder casting. This arrangement providessuiiicient heat for the. intake gases to prevent condensation, andthereby promotes uniform firing of the cy inders.

The exhaust ports 22, of which there are also six for each of thecylinder blocks, are connected to exhaust conduits or passages 36 whicharealso arranged longitudinally of the cylinder blocks and along theirouter edges. As shown, these conduits 36 are formed separately and aresecured to the cylinder blocks as by the bolts 37. It will be seen thatthe exhaust conduits are arranged parallel to the intake conduit 35, but

are outside of the valves.

The motor carbureter 38 is arranged between the cylinder blocks and isprovided with a short'pipe connection 39 which connects the carbureterwith conduits 40 which lead to-the intake conduits or passages 35 of thetwo cylinder blocks. These conduits 40 are indicated in dotted lines inFig. 2 and are preferably formed as an integral part of the castings.The conduits 40 pass between two of the cylinders in carrying the gasesfrom one side of the cylinder blocks to the other. a

Other forms of the invention will readily suggest themselves to oneskilled in the art, and the claims are understood as not limited to theexact form of the invention shown herein.

nally of the cylinder block and arranged between the valves and thecylinder bores, and means for operating the valves.

2. In a multi-cylinder hydrocarbon motor, the combination of a cylinderblock having cylinder bores and valve seats, valves for said seats, theaxes of the valves and cylinder bores being at acute angles to eachother, intake and exhaust conduits extending longitudinally of thecylinder block and arranged on opposite sides of said valves, and meansfor operating said valves.

3. In a multi-eylinder hydrocarbon motor, the combination of a cylinderblock having cylinder bores and valve seats, valves for said seats, theaxes of the valves and cylinder bores being at acute angles to eachother, an intake conduit arranged between the valves and the cylinderbores, a carbureter on the side of the block opposite to the valves, anda conduit extending throu h the block from the carbureter to said intaieconduit.

4. In a multi-cylinder hydrocarbon motor, the combinat'io of a crankcase, cylinder blocks arrangedin V'position thereon, intake conduits onthe outside 'of said blocks, a carbureter between the cylinder blocks,and conduits connecting the carbureter and intake conduits.

5. Ina multi-cylinder hydrocarbon motor, the combination of a crankcase, cylinder blocks arranged in V position thereon, intake conduits onthe outside of said blocks, a carbureter between the cylinder blocks,and conduits passing through the cylinder blocks and connecting thecarbureter and intake conduits.

6. In a multi-cylinder hydrocarbon motor,.the combination of a crankcase, cylinder blocks arranged in V position thereon, and having intakeports along their outer edges, a carbureter arranged between thecylinder blocks, and conduits leading from the carbureter to therespective intake ports.

7. In a multi-cylinder hydrocarbon m0- tor,the combination of a crankcase, cylinder blocks arranged in V position thereon and having integralintake passages east along their outer sides and having intakeportscommunicating with said passages, a carbureter arranged between saidcylinder blocks, conduits connecting said carbureter with said intakepassages, vertically arranged valves for said ports, cam shafts foroperating said valves, and means for driving said cam shafts.

In testimony whereof I affix my signature in the presence of twowitnesses.
